Which term describes someone who is very careful and attentive to details?

The term that describes someone who is very careful and attentive to details is "meticulous." This word conveys a sense of precision and thoroughness in the way a person approaches tasks, ensuring that no detail is overlooked. A meticulous individual often pays close attention to every aspect of their work or environment, reflecting a commitment to excellence and accuracy. This quality is highly valued in many fields, especially those that require a high degree of care, such as editing, design, research, and craftsmanship. The focus on detail associated with meticulousness underscores the importance of diligence and conscientiousness in achieving quality results.

In contrast, options like "obsolete," which refers to something that is no longer useful or relevant, "pious," which denotes devoutness and religious devotion, and "presumptuous," which characterizes a person who oversteps boundaries or is excessively forward, do not relate to carefulness or attention to detail.
